Amateur video shows St. Bernard shouting up to the girl, trying to talk the girl into going back into her apartment. Suddenly, the girl falls, eliciting horrified screams from neighbors.

But St. Bernard catches her in his arms, stumbling slightly forward to the ground with the girl still firmly in his grasp.

"I picked her up and carried her, and I was holding her, rubbing her, and she just more or less kept looking around," he told NBC 4 New York. "She never closed her eyes, she didn't lose consciousness."

The girl was not wearing pants, and St. Bernard wrapped her in his MTA uniform shirt as he waited for paramedics to arrive.
